Abstract

A solids removal and concentrating unit. The unit comprises a tank (22), with an inlet line, an outlet line (5), and a sludge removal line (20). The unit further comprises a plurality of linear baffles (28) positioned in the tank forming a baffle row, with the baffles being positioned in substantially vertical oreintation. The tank has a plurality of these baffle rows. The baffles reduce the velocity of a carrier liquid and form slight vortices in the liquid behind the baffles to facilitate the downward movement of solids.
